1 Claim. ('01. l976) This invention relates to means for cleaning lint cotton after it leaves the gin and while it is being conducted to the main lint flue, it being possible through the use thereof to separate forsign matter from the lint by gravity, the cleaner being readily adjustable toadaptit for cleaning cotton lint of different types such as green or dry or trashy or clean.

It frequently happens that considerable trash passes through the saws with the lint after the seeds have been extracted but by providing a claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention has been shown. A

In said drawings i Figure 1 is a view partly in side elevation and partly in section of a portion of a gin, a portion of the main flue used to conduct lint to the press, and a connecting flue provided with the present improvements.

Figure 2 is a view partly in top plan and partly in section oi. the structure shown in Fig. 1.

Figure 3 i an enlargedsection on line 3-3,

Figure 4 is a section on line 4-4, Figure 3.

Referring to the figures by characters of reference, I designates a portion of a gincontaining the gin saws, etc., and 2 designates the main flue utilized for carrying the lint to a press. Asa general rule one of these flues is connected to several gins. In the present case it i shown connected to a single gin by means of a lint flue 3 through which lint from which the cotton seeds form of a slide which can be open for the purpose of cleaning the separating chamber.

Parallel shafts Band I are journalled in the side walls of the separating chamber 4 and extending upwardly from the shaft 6 and fixed thereto so as to move therewith is a p'late 8 extending throughout the width of chamber land constituting a baflie. The upper end portion of this plate is bent at an acute angle away from the large end of the flue to provide a Wing 9 and the angle portion IQ of the baffle is so positioned that when it is in contact with the adjacent wall of chamber 4, the wing 9 will be substantially in line with the bottom of thelarge end of the flue. This is clearly shown in Fig. 4.

Another plate II is secured to the shaft 1 and is fixed thereto so as to move therewith and this plate has its upper end portion merging into a wing l2 disposed at an acute angle thereto, the angle portion [3 formed by the bafiie plate I l and its wing 12 being located at alltimes :above the level of the wing 9. When the wing 9 is in its lowermost position, as shown by broken lines in Fig. 4, and the baffle plate II is resting against the wing 9, wing I2 of baffle II will be in a plane substantially-parallel with the plane occupied by the wing 9 but below the level of the bottom of the small end of flue 3 as clearly shown in Fig. 4.

Shaft 5 has an arm M at one end secured thereto and provided with an operating rod I5. An-

other arm I 6 is fixedly secured to one end of shaft I and has an operating rod 11 secured thereto. Both rods are extended through openings 18 and 19 respectively formed in a bracket 20 secured to and extending laterally from the flue 3. Both rods are provided with teeth 2| along their lower edges for engaging the lower wall of the respective openings 18 and I9 whereby, following longitudinal adjustment of the rod, they can be dropped into engagement with the walls of the respective openings and thus held against further longitudinarmovement. Bothrods are prohave been removed will travel through the flue 2.

vided with handles 22 by which they can be manipulated readily.

At no time is thetop of the chamber 4 closed. When the bafile plates 8 and II are swung to the left in Figs. 1 and 4130 their extreme positions, they will be located as indicated by broken lines in Fig. 4 with the bottom of flue 3 and the wings 9 and I2 all occupying substantially parallel planes but with wing l2 spaced from that wall of chamber 4 nearest flue 2. By manipulating rod [1, however, bafiie plate II can be swung away from position shown in Fig. 4 or to any other desired baffle plate 8 to the full line position and the baiile plate 8 can similarly be adjusted to any desired position either in contact with or spaced from the balfle H and the wall of chamber 4. It is intended to adjust these baflies relative to each other so as to meet the requirements of the particular cotton lint to vbe cleaned.

It is to be understood that, when the lint leaves the gin, it frequently contains trash which should .be removed therefrom before it passes into theflue "2. The lint may be green or itmay be dry. It is intended to adjust the baffles so as to afford the most advantageous result in removing the foreign matter from the lint as it passes through flue 3 from the gin l. lint reaches the top of chamber 4 the heavier undesirable material mixed When the therewith will be deflected downwardly into chamber 4, gravitatingt0 the bottom thereof. If

the lint contains a considerable amount of trash, it is preferred to swing the bafiies upwardly as indicated, for example, by full lines in Fig. 4. If the lint is comparatively free of undesirable matter, however, the baflles can beswung downwardly to the positions shown ':by broken lines in Fig. 1. In any case sufiicient area will be provided to permit gravitation of foreign substances from the bottom of the flue into the chamber 4' and when a predetermined amount of this material has accumulated in the chamber, the slide bottom 5 can be opened and the collected material released therefrom.

Importance is attached to the fact that this cleaner is-located between the gin and the flue so that the lint is cleaned after the seeds have been removed therefrom. Thus the invention is distinguished from those employed in which the cleaning operation takes place before the seeds are removed, or during the seed-removing operation, neither of which operations are entirely satisfactory, if employed alone because some objectionable material frequently gin with the lint and it is this the present invention is designed What is claimed is: g

The combination with a gin and a lint flue extending across the gin, of a connecting flue extendingfrom the gin'to the lint flue, a dow wardly extending portion carried by the co 1l0 remove.

nesting flue and providing a separating chamb r,

that portion of the bottom of the connecting fl e betweensaid chamber and the gin being in a plane below the plane occupied by the remainder of the bottom portion of the connecting flue, separate bafiie plates within the separating'chamher and mounted to swing about parallel axes respectively, separate means for adjusting the respective baifle, plates an-gularly, said baffle plates being positioned with the upper ends thereof at different elevations within the upper portion of the chamber and between the planes of the upper and lower bottom portions of the connecting flue, and wings extending from the upper ends of the 'bafiie plates and away from the ends,said Wings being normallypositioned .1n separate planes parallel with the planes of' the two bottom portions of the connecting flue.
